ENVIRONMENT-FRIENDLY STARCH PAPER AND PREPARATION METHOD THEREFOR

摘要

An environment-friendly starch paper, comprising a three-layer composite structure formed by an upper layer of polylactic acid polymer raw material, a middle layer of papermaking masterbatch and a lower layer of polylactic acid polymer raw material, the ratio of the three layers being 1:8:1 in thickness. The papermaking masterbatch comprises the following components by mass percent: 30% of starch, 20% of polylactic acid polymer raw material and 50% of calcium carbonate raw material. The environment-friendly starch paper is produced by an environment-friendly method without using any heavy metal or plasticizer and can be completely degraded.
